PAPER-GAGE.

To @ZZ whom, t may concern.-

Be it known that I, WILLIAM SMITH, a subject of the King of GreatBritain, and a resident of the city of New York, borough of Manhattan,in the county and State of New York, have invented a new and ImprovedPaper-Gage, of which the following is a full, clear, and exactdescription.

My invention relates to paper-gages for machines for reproducing bystencils and the like.

Although capable of general use, I have chosen to illustrate myinvention as applied to the apparatus which forms the subjectmatter ofmy Patent No'. 639,623, granted December 19, 1899. That machine was designed for use with sheets of paper of one size. The principal object ofmy present invention is to provide means whereby machines of thisgeneral character can be operated in connection with sheets of differentsizes. For this purpose I provide movable or adjustable paper-guides onthe plunger of the machine and locate registering marks onv the plunger,stencil-holder, and stencil.

Another object of my invention is to provide for locating the printingportion of the stencil in any position that may be desired in view ofthe particular size of paper that is to be used.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a longitudinal sectional view taken on a vertical planethrough a portion of an apparatus of the character hereinbefore referredto, showing my invention applied thereto. Fig. 2 is a plan of theplunger. Fig. 3 is a bottom plan of .the stencil-holder and stencil; andFig. 4 is a sectional view, on an enlarged scale, of one-of the gages.

The table 10 of the machine is provided with a well 11, as usual, forthe reception of the plunger 12. This plunger may be operated in anydesired manner in order to force sheets ofvpaper 13, supported onitsupper surface, against the under surface of a stencil 14. This stencilis shown as being supported is a stencil-frame 15, which is providedwith a peripheral groove 16 for receivingthe edge of the stencil and astencil-holder 17. The stencil-frame may be secured over the opening inthe table by set-screws 18, as has been shown in my. aforesaid patent.The drawings also illustrate a front opening 19 in the well, throughwhich the plunger extends. In my previous machine the arts were soproportioned that they would) receive a desired size of paper-as, forexample, foolscap.v

` In order to 'fit the machine for operating upon paper of severaldifferent sizes, I provide the plunger with longitudinal grooves 20. Inthese grooves I place gage-pins 21 and mount these pins in such a mannerthat they can be adjusted alongthe grooves and secured in any desiredpositiontherein. It is intended that the edges of the pile or pad ofpaper upon which the impressions are to be made shall engage with thesides of the pins and be thereby fixed in the position which is desired.In order to provide for securing the pinsv in adjusted positions uponthe plunger and for mounting them in such a manner that they will yieldwhen they approach the stencil on the upward movement of the plunger, Iprovide pin-holders 22. Each of these holders is preferably in the formof a tube having a flange 23 upon its upper end, this iiange resting ina counter# sunk opening 24, surrounding the slot 20, and the top of theflange being flush with the top of the plunger. The tubes may extenddown below the bottom of the plunger and are provided with closed lowerends, and in said tubes are mounted springs 25 for supporting theplungers and keeping them in elevated position. Each tube is alsoprovided with means for securing it to the plunger in any adjustedposition, this being illustrated in the form 0f a nut 26, engagingscrew-threads 27, on the outside of the tube. A washer 28 is also shownabove the nut. I have shown .a stationary bar 29 and an adjustable bar30 across the bottom of the stencil. The latter bar is adjusted so as toengage the pins 21.

In order to provide for indicating the positions at which the pins areto be set, I have shown a series of transverse lines indexedor marked 12 3, &c., across the surface of the plungernear one edge. Thecorresponding edges of the stencil and holder are also provided withsimilar lines indexed or marked in the same way. I have also shown theplunger, stencil, and holder as being provided with a series oflongitudinal lines in- IOO IOS

deXed or marked a b c d, Sac. The lines of each set are designed toregister with the lines designated by the same characters of the othersets.

The manner of using the device and the operation of the parts is verysimple. With the paper that is to be printed upon placed upon theplunger or upon a stencil-sheet the operator can readily see theposition in which the printing parts of the stencil will have tov comeand can locate the same with reference to the numbered and letteredlines on the stencil or plunger. stencil-sheet in av type-writer andlocate the characters at the desired points, so that they will print inthe desired place on the paper when the paper and stencil are placed inproper position on the machine. When prepared, the stencil is placed onthe holder and centered by the lines, so that the lines on it willregister with the corresponding lines on the plunger. The pile or pad ofpaper is then placed on the plunger with two edges flush with the edges,of the plunger. When this has been done, the operator adjusts thegage-pin holders 22 in the slots 20 so that the pins will come againstthe rear edge of the paper. When the plunger is elevated to bring thepaper into contact with the stencil, the top of the gage-pins willengage with the bar 30, and the pressure exerted will force themdownwardly against the force of the spring 25. It will be found thateach sheet is printed in the predetermined place.

Instead of the marks on the stencil-holder there can be used anyregistering device which will insure that the stencils will all beplaced in the proper position with respect to the holder, which holderis of course held in registration with the plunger by the walls of thewell.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.
